SELF-CLOSING FAUCET.

" SPECIFICATION forming part of Letters Patent No. 291,668, dated January 8,. 1881:.

Application filed April 18, 1883.

To all whom it. may concern Be it known that we, SILAS BARKER and SAMUEL L. BARKER, of- Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Self-Closing Faucets; and we do hereby declare that the following is a full, clear, and exact description thereof, whereby a person skilled in the art can make and use the same, reference being had to .the accompanying drawings, and to the letters of reference marked thereon.

Like letters in the figures indicate the same parts. I

Figure 1 is a top view of our device. Fig.

2 is a view in longitudinal vertical section on plane denoted by line X X of Fig. 1, showing valve closed. Fig. 3 is a view in longitudinal section, showing valve open. Fig. 4 shows detail sectional views of one form of valve and packing. Fig. 5 is a detail view of an alternate form of valve. Fig. 6 is a detail View of the adjustable valvebperating arm.

Our invention relates to the class of fluid: cocks known as self-closing, and it consists of the improved combination of parts by which the valve is automatically closed without the use of a spring.

The accompanying drawings represent our invention as applied to a faucet of ordinary construction; and the letter a denotes the body of the faucet as a whole, attached by means of screw-threads to the plug b, which bears a stop-cock, c. The faucet is provided with the branch cl, through which the operating parts may be inserted within the faucet, and is closed by a screw-cap, e, suitably packed. The spindle f, in the form shown, is arranged transversely of the branch, bears on its outer end the operating-handle g and within the faucet the crank h, which is fastened to the spindle by means of a key or the clamp-screw z, as shown.

To the lower end of thecrank is pivotally connected a rod, j, having stop k, and at its outer end the adjustable arm I, the end of which is in contact with the face of the diskshaped valve m. The rod j slides in. the

(No model.)

socket or guide a, fast to the body of the faucet, and its play is limited by means of the shoulder in contact with the face of this guide.

, The valve m is preferably circular in form, and is provided on its face with an annular packing, m, of soft material-as leather or the like-which packing is held in place by means of the'radial pins driven through the flange of the valve into the packing. The valve may be made wholly of soft material, strengthened or re-euforced by the pins driven through and into it radially and edgewise. This valve is arranged to operate in a chamber, a, formed between the valve-seat 'n and the end I) of the plug. 6

The operation of our device is as follows: When it is secured to a line of water-pipe, the water forces the valve to itsseat, as shown in Fig. 2, and closes the faucet. The faucet is opened by turning the handle g in such a way as to push the valve back from its seat by means of the rod and arm, as shown in Fig.

3. The amount of play of the valve is determined by means of the adjustable arm Z, which is provided, preferably, with a rounded head, as shown.

The valve-operating spindle may be arranged vcrtically, if desired, and we do not limit ourselves to the special arrangement and combination of parts here shown, as the main 8o feature of our invention consists of the loose valve m. operated in closing and held to its seat by the pressure of the water.

The plug and stop-cock c are not essential parts of our invention, but are convenient when it is desired to remove the faucet to repair the valve.

We claim as our invention 1. In combination, the faucet-body a, having the valve-chamber a. and the seat a, the disk-shaped loose valve m, and the valveoperating mechanism, all substantially as described.

2. In combination, in a self -closing faucet, the body a, loose valve m, rod j, with ad- 5 justable arm Z, and valve-operating mechanism, allsubstantially as described, and for the purpose set forth. a

wuses 3. In a self-closing faucet of the kind 11ercstantially as described, and for the purpose in described, in combination, the faucet-body set forth. a, provided with guide a, spindle f, bearing crank h, and the rod j, having stop 70, all sub- 5 stantially as described.

4; The loose valve m, having a mortised WVitnesses; face, in which annular packing m is secured CHAS. L. BURDEIT, by means of radial pins or the like, all sub- H. C. YOUNG.
